Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Onboard telematic monitoring devices in telematics systems are dependent on vehicle power, leading to interruptions and inaccuracies in data collection and communication when power is lost or unstable, such as when the vehicle is turned off or in the event of a disconnection.
Innovation Solution
A battery device with control circuitry that operates in multiple modes to provide power to telematic monitoring devices, including charging, full power, low power, and disconnection modes, using data from sensors like ignition, voltage, acceleration, and audio to determine the vehicle's state and adjust power provisioning accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If telematic monitoring devices are dependent on vehicle power, then the device complexity is reduced, but the reliability of data collection and communication deteriorates when power is lost or unstable
Solution Approach 1:
The battery device charges in advance when vehicle power is available, storing energy before it is needed. The control circuitry monitors vehicle power status and proactively charges the battery when the vehicle is on, ensuring power is ready before a potential disconnection or vehicle shutdown occurs.
Solution Approach 2:
The battery device acts as an intermediary power source between the vehicle power system and the telematic monitoring device. It buffers power fluctuations and provides continuous power to the monitoring device, isolating it from vehicle power instability or disconnections.
2Reliability
If the battery device operates in full power mode continuously, then the telematic monitoring device maintains optimal performance, but the energy consumption increases
Solution Approach 1:
The battery device dynamically adjusts its power output based on real-time conditions. The control circuitry monitors vehicle status, motion state, and power availability, switching between full power mode, low power mode, and charging mode to optimize energy usage while maintaining necessary monitoring functions.
Solution Approach 2:
The system changes power delivery parameters based on operational context. When the vehicle is moving or on, full power is provided; when stationary or off, low power mode is used. The control circuitry adjusts voltage and current output levels to match the actual needs of the monitoring device.
3Quantity of substance
If the battery charges continuously when vehicle power is available, then the battery capacity is maximized, but the power provisioning to the telematic monitoring device may be insufficient during vehicle shutdown
Solution Approach 1:
The control circuitry continuously monitors the battery charge status and vehicle power availability, using this feedback to make intelligent decisions. When the battery is charged and the vehicle is on, the system can afford to power the monitoring device. When the vehicle shuts down, the feedback mechanism ensures the battery has sufficient charge to take over.
